IMPROVEMENT IN COPS FOR SEWING-MACHINES.

.mak-ing a part of this specification, in which- Figure I is a View of acop or bobbin as taken off the winder 'or machine by which it is made.Fig. II is a View of a cop or bobbin as it is placed in a shuttle; -andFig. III is a view of a shuttle thus containinga cop or bobbin in itsrace, with the end of its thread projecting; and Fig. IV is a cap soconstructed as to draw lits thread from the side thereof.

v @More particularly: In Fig. I, A is the cop orbottom. It is spirallywound. B isthe internal end ofthe thread emerging from the insidethereof by a hole at one end. It 'is a spirally-wound mass of threadrecurving at each muh-alternately, until it is wound large enough tofill the shuttle, when a few circular windings are given upon the wholemass preparatory to securing this end of the thread, and then by aloop-knot or other similar and equivalent Inode the external end of thethread is fastened.

The Inode of constructing this cop, bobbin, or mass of thread is asfollows: I take a suicient quantity of thread--be the article I desireto use, silk, linen, cotton, or otherv Inaterial-and I'attach it to thedistal end or protruding end of the spindle, on which I wind the cop. -Ithen revolve the spindle a few times, which puts on the`spindle,nearlycircular windings in immediate contact with the spindle;and whenthese nearly circular windings are about the length ofthe cop Iwish to complete, I then lay the thread in a guide and continuerevolving the spindle, which tends to give circular windings, while theguide tends to move the thread parallel to the lon-4 gitudinal axisofthe spindle. The combined action, therefore, of the spindle and guideis that' the cop is wound spirally and to the length to which the guideis set or gaged. A

recurve is of course made somewhat abruptly at each end by thealternating or reciprocating ternal end so that it may not slip andbecome` tangled.' I give this description because it best-describes thenature of the cop. -But in so doing the windings. nearly circular atfirst, are not essential, foi-if the spindle is rough enough so that thethread will not slip upon it, then the thread may be put into the guidewithout them. And as to the last circular vwindings,l they are notessential, as the end may be fastened by other means, as a little pasteor glue; or a paper may be wound about the whole to preserve the shapeand facilitate the operator of a sewing-machine while handling aquantity of cops, the'I last object being merely to secure the externalend, and of the former to 'commenceY the corp properly;

but the combined actionof the spindle and guide is essential, or theirequivalents, in orderto make a cop spirallywound, and drawing or feedingout its thread from the inside thereof until it exhausts the whole cop.The

machine by which this is done, not being claimed in this specification,is not figured nor described; but the cop thus Vmade is described, thatthe use of it in sewing-machines may be described not only,but claimed.4It is believed that the flow or feeding out of the thread of this cop issteady and even, and is of `great utility in making tension on theshuttlc-thread, as well as a very convenient and useful Inode of placingthread in the shuttle.

By Fig. II, I design merely to show a cop which draws or feeds out orpays out its thread from the inside thereof lin a shuttle, thusexhibiting further its use in sewing-machines. C is the shuttle, with acop lying in it; and I) is the internal end of the cop passed through ahole in the side of the shuttle, a series of holes inthe side of theshuttle near D, or a friction-needle, or other means making the nec- 5essary tension on the thread, which means, not being claimed in thisspecification, are not fignrednorl described, said tension, meaning the0f the cop there are inany varieties and tightness given to the thread1after it has left the oop, the iiow or feeding out of the cop beinguniform and even.

Fig. III is a shuttle-race, with a shuttle 1ying in it. E -E is therace; F is the shut-tie, with the -internal end of the eopthreadprojecting from one of the holes in the side of the shuttle. .G is thepoint or piace Where the needle plunges of the sewing-machine. Theaction and use of the shuttle and race is familiar to those skilled insewing by machinery, to which art it appertains. The object of this.gnre is further to exhibit the use of the cop l in sewing-machines asconnected with niaehines using a needle and shuttle, or theirequivalents.

By Fig. IV, I show a variety of Fig. I. In it H is the oop and I theinternal end of the Hiread, emerging by a hole in The side instead Ofthe end thereof.

equivalent-s, wound in a great variety of Ways. In describing` them, themain feature would ,be any and al1 masses, cops, 0r bobbins, drawing thethread from the inside thereof.

' What I elaim as my invention, and desire to secure by Letters Patent,is-

The use of a cop or bobbin Without spindle or spool, in combinationwitha shuttle, or what is equivalent thereunto, when the thread is drawn orfed out from the inside of the cop or bobbin, by which means l secure anuni-4 form tightness-or tension on the cop or bobbin thread as it isydrawn or fed out from the shuttle, as described.
